Top Metrics You Need to Understand When Measuring Front-end Performance
Since properly measuring the FID requires real user interaction, you can’t simply scan a website and get that value. However, you can add code to your application to get that information. Once you have, it’s up to you to do whatever you want with it. Google has an open-source script you can use directly inside your page to measure this metric: https://github.com/GoogleChromeLabs/first-input-delay

Top 20 Frontend Interview Questions With Answers
Google Core Vitals now represent the most important metrics to focus on when it comes to technical SEO. Google Core Vitals are a set of standardized metrics that Google uses to evaluate the user experience offered by a web page and assign it a technical SEO grade. Several tools exist to measure and report technical SEO performance, but the most reliable is Google Lighthouse.

Is Lighthouse a misleading performance tool?
Let's go back to 2020, this was when Google made a big change regarding their performance rating -- they introduced the Core Web Vitals. I want to discuss this timeframe because it was the last point where there is clear comparable data between the performance metric set (5 metrics) and the Core Web Vitals (3 metrics). The Core Web Vitals is a subset of the performance metric set.

What Next.js Has to Offer React Developers
Beyond elevating the user experience, another clear benefit of speeding up the rendering of a website is search engine optimization (SEO). Speed is so important to ranking well on search engines that it’s included in Google’s published description of what their indexers use to rank websites for performance, called Core Web Vitals.

Climate-friendly software: don't fight the wrong battle
This is something we won't ever be able to measure, as it depends on how people perceive the overall experience on their device, but it boils down to perceived performance. So by all means, optimize your mobile apps and web frontends, test on old devices and slow networks (even if only emulated), and monitor their real-user performance (e.g. through Web Vitals). As part of performance testing, have a look on electricity use, as it will both be directly associated with emissions to produce that electricity, and be perceptible by the user (battery drain). And don't forget to account for the app downloads as part of the overall perceived performance: light mobile apps that don't need to be updated every other day, frontend JS and CSS that can be cached and won't update several times a day either (defeating the cache).
